Heat makes the Subaru engine function well, but too much heat is dangerous for the system. That's why the system needs something to maintain its temperature in the operational range. The vehicle's cooling system takes care of that. The air intake system also helps in that task by giving the engine dense cold air for its power production. Does this mean that the air intake system must bring more air into the combustion chambers? Too much amount of air filling the engine will affect the efficiency of the combustion process, and high level of toxicity in the emissions will be another problem.
